Erosion Study of 7.62mm CR-MO-V Steel Gun Tubes. Part 1. Erosion Analysis and Characterization. Part 2. Fatigue Behavior in Reactive Environments

Abstract

The erosion process in 7.62mm steel gun barrels has been chronologically characterized by investigation of the test-fired barrels fired from 1 to 3000 rounds. Both unplated barrels and barrels with hard chromium plated bores were included. Detailed metallurgical analysis, using modern analytical techniques, was conducted on the test-fired gun barrels. Evidence is presented to demonstrate that chemical effects substantially augment the erosion phenomenon caused by thermomechanical factors. Gas-metal reactions and chemical attack involving Pb, S, Cu (Cu-Zn) and Ca comprise the observed chemical effects.
